Classic method for exiting multiple activities in Android

1. Use the list collection method

Save the activity instance with a list and kill it one by one

Add similar code in oncreate method of each activity:

When it is necessary to exit the program, call:

SysApplication. getInstance(). exit();

In short, the reference of each activity is added to a global linked list through the singleton mode, and the system is called every time the program exits When exit (0), first call the finish method of the activity in the linked list

Advantages: simple implementation and clear logic

2. Use broadcasting

recommend!! So convenient!!

The basic logic is to define a BaseActivity, bind the broadcast in this Activity, and invoke finish () in the broadcast onReceive method. Then, all future activities inherit this activity, send broadcast when exiting, exit baseactivity, the parent activity exits, and the child activity definitely exits.

The code is as follows:

An activity instance:

This is called at the exit:

Advantages: convenient, convenient!! Just send a broadcast where you exit!!

This is my exit output:
